COFFEE-BOILER.

SPECIFICATION forming part of Letters Patent No. 523,656, dated July31', 1894.

Application filed $eptemher 27, 1893. serial No. 486,686- (No model.)

To all whom it may concern:

a citizen of the United States of America, re-

siding at Bridgewater, in the county of Rock ingham and State ofVirginia,-have invented certain new and usefullmprovements inCoffee-Boilers, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to certain new and useful improvements in coffeeand tea pots.

1he object of the invention among other thlngs is to provide a novelsteeper in comblnation with and applicable to any wellknown form ofcoffee or tea pot, the construction of the steeper being such, that thecoffee or tea shall be confined within a suitable chamber whichcommunicates with the main boiler, and at the same time so locatedas toform part of a casing through which a continuously moving current ofwater passes.

A further object is to employ such novel construction by which theaction of applied heat to the main boiler shall tend to constantlyagitate the liquid and form the same into a current, the course of whichwill be automatically directed upwardly through the chamber containingthe coffee, teaor other substance, thereby effecting a thoroughextraction of the volatile elements which are at once condensed, anddistributed through the liquid until it becomes saturated.

A further object is to provide simple and convenient means by which thesteeper may be readily separated or taken apart for purposes ofcleansing, repairing, &c., which is an important feature of myinvention, since the production of good coffee or tea necessarilyrequires that all foreign substances, small adhering particles of stalecoffee, 820., be first removed. I

With these and other objects in view, the invention comprisesvariouscombinations, arrangements and details which will be hereinafter fullyset forth and specifically pointed out in the claim following thedescription.

In describing the invention in detail, reference is had to theaccompanying drawings which form part of this specification, and

wherein like letters indicate corresponding parts in the several views,in which Figure 1, is a central vertical sectional view showing awell-known form of coffee or tea pot with one form of steamer embodyingmy improvements applied thereto. Fig. 1, is a horizontal section viewtaken about the line 0:, x, of Fig. 1. Fig. 2, is a similar View,showing in detail a modified form of steeper with the parts detached orseparated. Figs. 3, ,4 and 5, are similar views showing furthermodifications. 1

In the drawings, A, denotes a common form of coffee pot which isprovided interiorly and adjacent to the mouth with suitable formed lugsa, arranged diametrically opposite each other.

B, represents the steeper, and 1), spring metal arms, which projectradially from the vertical tube b and engage the under sides of the lugsa, thereby securely holding the steeper at all times in proper positionto allow for the immersion and draining the pot, without necessarilyremoving the steeper. At the base of this tube b that is at the point ofconnection with the downwardly and out- ;wardly flared cup b a screen 15is either rigidly secured as in Fig. 1, or removably held in position asin Figset and 5, and immediately above the screen several openings 6 areformed in the tube for a purposeto be hereinafter described; I), is thecofiee chamber of the steeper, which is closed at the upper end by thecap'and screen 15*, b and provided with a base b flared to fit snuglywithin the pot A, and having a dividing screen b at tffe point ofconnection with the wall of the chamber. This flared base incloses andforms what is herein known as the steam generating chamber and may berigidly or detachably secured as shown in Figs. 1 and 2,

and with the screen fixed or removable as desired.

In Fig. 3, the steam chamber is enlarged by slightly reducing thediameter of the coffee chamber and extending the wall of the flared baseto the mouth of said chamber. At

the same time, afurther advantage is gained by this'a1teration,viz.,steam or hot air is introduced through a series of openings locatedsubstantially centrally of the length of the coifee chamber, therebyaiding materiallyin readily separating the volatile elements of thecoffee.

Referring to Figs. 2 and 4, I have shown detachable screens; in theformer, the screens are of a shallow disk-like shape, while in thelatter they are more nearly approximate a cup-shape and are soproportioned as to fit one within the other.

The operation is as follows: Owing to the location of the coffeechamber, that is to say, directly above, yet out of contact with thebottom of the boiler or pot, it is possible to steep any desiredquantity of cofiee and assuming that the proper amount of coffee hasbeen placed within the chamber and the steeper secured as aforesaid,water is poured into the boiler and heat applied thereto.

On reference to the drawings, it will be observed that the flaring baseof the steeper entirely covers the bottom of the boiler, there fore themain portion of steam generated must of necessity be inclosed'andconfined within this chamber, with only one passage for es cape, whichis through the cofiee chamber. Again, it has been found advantageous toslightly obstruct the upward flow of the steam after entering the coffeechamber, and retain it for atime therein. To accomplish this, the

upper screen has been given a reduced diameter, that is, about half thatof the lower, thus the elements will be more speedily volatilized owingto the continued action of the confined steam. As the steam and releasedelements pass from the coffee chamber, they escape through the openingat the base of the steeper-tube and are condensed before rising to thesurface of the water in the boiler, which results in obvious advantages.

As the water contained in the steam chamber becomes converted into steamand passes upwardly, the pressure of air in the boiler will force thepartially saturated liquid under the flared base of the steeper torefill the chamber, as above described.

It may be also mentioned that by the peculiar construction of thevertical tube -b a common objection, viz., boiling over of the liquid,is effectually overcome.

Having fully described my invention, what Iclaim as new, and desire toobtain by Letters receiving chamber provided with a detachable flaredbase, a tapering cap having centrally thereof a vertically projectingtube and openings formed at the point of connection, and screens withinand forming the top and 1 bottom of said chamber, as specified.

In testimony whereof I affix my signature in presence of two witnesses.
